AMD would not plan Ryzen 9 with 3D V-Cache for this series.
The notable absence of the Ryzen 7 7800X among the four Ryzen 7000s made official at the end of August suggests that AMD reserves this number for a processor benefiting from 3D V-Cache technology – the direct successor of the Ryzen 7 5800X3D in short. Anyway, on an AMD roadmap published at the end of September, there were indeed such chips. User ECSM_Official reported on Bilibili that the company will release two Ryzen 7000 3D V-Cache processors in the first half of 2023: a 6-core CPU (Ryzen 5) and an 8-core CPU (Ryzen 7). Above all, he announces that there will be no Ryzen 9 of this type (12 and 16 CPU cores).
The predictions of ECSM_Official remain of course hypothetical, but are quite credible. To tout the benefits of 3D V-Cache, a technology that grants more L3 cache to a processor, the company has, in the case of the Ryzen 7 5800X3D, focused its communication on earnings in video games. However, in this field, the interest of a Ryzen 9 for the majority of players is questionable, both financially and in terms of performance. In fact, the majority of players prefer a Ryzen 5 or a Ryzen 7; Ryzen 9 3D V-Cache, logically more expensive than classic Ryzen 9, would only concern a few customers.
In addition, Ryzen 9 3D V-Cache would perhaps induce more hardware constraints. Already for the Ryzen 7 5800X3D, this technology leads to some concessions: a voltage of 1.35 V lowering the frequencies compared to the Ryzen 7 5800X and prohibiting CPU overclocking.
What gains for Zen 4?
The contributions of an increased quantity of L3 cache for the Zen 4 CPU architecture remain of course to be defined. A few weeks ago, Tom from the MLID channel suggested a difference of about 30% between the Ryzen 7000 and the Ryzen 7000X3D. In the case of Zen 3, it brings substantial gains to the Ryzen 7 5800X3D in games. On average, this processor competes with the Core i9-12900KS at 1080p and 1440p; does as well as Ryzen 7 7700X.
A620 and Ryzen 7000 APUs
To be exhaustive, the ECSM publication also mentions the A620 chipset, apparently planned for the second quarter of 2023, and an AM5 APU which would natively support memory at 4800 MT/s, against 5200 MT/s for the Ryzen 7000 Raphael.
